Description
Technical field
The present invention relates to the environmental protection equipment in the industries such as the energy, environmental protection, chemical industry, pharmacy, building materials, be specifically related to a kind of rotation demister, when needing to remove in gas environment or the harmful droplet of follow-up equipment, demister can be utilized to carry out demist, be applicable to have droplet to exist in the gas flow and need to carry out the occasion of gas-liquid separation.
Background technology
The BACKGROUNDToday society of demist, environmental problem is on the rise along with industrialized process, and atmospheric issues is particularly outstanding.Recently, the PM in air
2.5it is the multiple main cause of haze that content raises, and the droplet in tail gas is a major incentive.With desulfurization citing, carry a large amount of droplet in the flue gas produced in thermal power generation process, the salt in droplet and dust combine and form PM
2.5core, simultaneously steam enters air is PM
2.5formation create condition, and PM
2.5very large to the harm of health, therefore requirement is proposed to the small particle diameter droplet trapping ability of demister.
Current demister many employings template demister, the inertial collision of main dependence droplet realizes demist, although this method demisting efficiency is very high, but to small particle diameter droplet substantially without demist ability, and demist is not separated with cleaning process, add the probability of secondary droplets, although use more pocket type demister demist ability to increase, to PM in addition
2.5deng droplet still without positive effect.For existing mesh mist eliminator and electrostatic precipitator, the former because the crystal salt of slurries droplet and precipitation easily between silk screen structure result in blockage and cannot normally run, the latter is put a difficulty because above-mentioned substance causes at electrode surface incrustation and cannot normally be run equally.Patent " a kind of drum-type electrostatic precipitator " (patent No. 03110922.5, publication number CN1519054A, publication date 2004.8.11) discloses a kind of dust arrester, and this device comprises electrostatic precipitator, control device and cleaning device.The advance of its design philosophy is to have carried out twice electrostatic precipitation process, but its Problems existing does not allow gas pass cylinder, have lost inertia trapping effect, and it is inapplicable for demist, because cleaning section and circuit are not disconnected under the high humidity environment of fog, be easily short-circuited phenomenon.
